Device for the determination and analysis of the motor skill and the oculomotor skill of a person

Abstract

The invention relates to a device for the determination and analysis of the motor skill and the oculomotor skill of a person ( 100 ), with a headset comprising at least the following components: a display unit ( 9 ) for displaying an image to the eyes of a person ( 100 ), when the headset is mounted on the head of the person ( 100 ); an optical sensor system ( 3, 4, 6 ) for estimating the position and shape of an object in three-dimensional space and for estimating the position of the head set in three dimensional space, wherein the optical sensor system ( 3, 4, 6 ) is arranged and designed for the detection and registration of the hands and fingers of the person ( 100 ); an eye-tracking module ( 8 ) that is configured to determine a point of gaze of the person ( 100 ) wearing the device. The invention furthermore relates to various methods for using the device.

The invention claimed is: 
     
       1. Method for analyzing the motor skill and the oculomotor skill of a person ( 100 ) with a device, comprising the steps of:
 Estimating a three dimensional surrounding of the person with the device, 
 Displaying an object arranged in the three-dimensional space surrounding the person with the display unit of the device, 
 Determining the position and shape of the hand and the fingers of the person pointing towards the displayed object with the optical sensor system, 
 Determining a pointing direction or a point of contact of the object and a finger of the person from the position and shape of the hand and the fingers, 
 Determining a deviation of the position of the hand or the pointing direction of the fingers and the position of the displayed object, 
 
       wherein the devise comprises:
 a headset, 
 a display unit ( 9 ) for displaying an image to the eyes of a person ( 100 ), when the headset is mounted on the head of the person ( 100 ), 
 an optical sensor system ( 3 ,  4 ,  6 ) for estimating the position and shape of an object in three-dimensional space and for estimating the position of the head set in three dimensional space, wherein the optical sensor system ( 3 ,  4 ,  6 ) is arranged and designed for the detection and registration of the hands and fingers of the person ( 100 ), 
 an eye-tracking module ( 8 ) that is configured to determine a point of gaze of the person ( 100 ) wearing the device. 
 
     
     
       2. Method according to  claim 1 , wherein the method further comprises the steps of:
 Determining a point of gaze with the eye-tracking module, 
 Determining a deviation between the point of gaze and the objects position. 
 
     
     
       3. Method according to  claim 1 , wherein the displayed object is moving along a predefined trajectory, the method further comprises the steps of:
 Determining a temporospatial deviation between the position of the hand or the pointing direction of the fingers and the displayed object trajectory, 
 Determining a temporospatial deviation between the point of gaze and the displayed object trajectory. 
 
     
     
       4. Method according to  claim 1 , wherein the method further comprises the steps of:
 Providing a predefined minimum step length and a minimum step frequency, 
 Displaying an object to the person with the display unit, when the determined step length and/or step frequency is lower than the predefined minimum step length and/or step frequency, and/or 
 Issuing an audio signal particularly with an audio unit such as a speaker comprised by the headset, when the determined step length and/or step frequency is lower than the predefined minimum step length and/or step frequency. 
 
     
     
       5. Method for determining eye movements and hand tremor with a device comprising the steps of:
 Determining the eye movements with the eye-tracking module, 
 Determining the position and shape of the hands of the person wearing the device with the optical sensor system, 
 Comparing the determined eye movement and the determined position and shape of the hands, 
 
       wherein the devise comprises:
 a headset, 
 a display unit ( 9 ) for displaying an image to the eyes of a person ( 100 ), when the headset is mounted on the head of the person ( 100 ), 
 an optical sensor system ( 3 ,  4 ,  6 ) for estimating the position and shape of an object in three-dimensional space and for estimating the position of the head set in three dimensional space, wherein the optical sensor system ( 3 ,  4 ,  6 ) is arranged and designed for the detection and registration of the hands and fingers of the person ( 100 ), 
 an eye-tracking module ( 8 ) that is configured to determine a point of gaze of the person ( 100 ) wearing the device. 
 
     
     
       6. Method for determining irregular eye movements and irregular hand movements with a device, comprising the steps of:
 Determining an eye movement of the person with the eye-tracking module, 
 Determining the position and shape of the hands of the person wearing the headset, 
 Comparing the determined eye movement and the determined movement and/or shape of the hands against one or more predefined temporospatial parameters and/or patterns, 
 
       wherein the devise comprises:
 a headset, 
 a display unit ( 9 ) for displaying an image to the eyes of a person ( 100 ), when the headset is mounted on the head of the person ( 100 ), 
 an optical sensor system ( 3 ,  4 ,  6 ) for estimating the position and shape of an object in three-dimensional space and for estimating the position of the head set in three dimensional space, wherein the optical sensor system ( 3 ,  4 ,  6 ) is arranged and designed for the detection and registration of the hands and fingers of the person ( 100 ), 
 an eye-tracking module ( 8 ) that is configured to determine a point of gaze of the person ( 100 ) wearing the device.
